friTap 2.2.1

What's Changed

• Telegram / MTProto Decryption (still early version - needs more tests; currently only Android)

• Added new mtproto and telegram keylog handlers that write MTPROTO_AUTH_KEY (cloud chat) and MTPROTO_E2E_KEY (Secret Chat) lines into a single combined keylog.
• Added an offline MTProto decryptor — TCP reassembly, obfuscated-transport de-obfuscation, and AES-IGE record decryption matched by auth_key_id.
• Added an offline Secret-Chat (E2E) decryptor that peels the second AES-IGE layer keyed by the per-chat key_fingerprint.
• Docs: [Telegram (MTProto)](https://fkie-cad.github.io/friTap/protocols/telegram/).

• Passive Analysis (--scan) - still experimental (early version)

• Added the PrivacyAnalyzer for PII detection (email, phone, PAN via Luhn, IBAN via mod-97, SSN, IMEI, MAC). Findings are redacted by default; reveal with --scan-show-pii.
• New report filters: --scan-category (secret,pii,network,protocol), --scan-min-confidence, and --scan-source.
• Docs: [Traffic Analysis](https://fkie-cad.github.io/friTap/advanced/traffic-analysis/), [CLI Reference](https://fkie-cad.github.io/friTap/api/cli/).

• External Analyzers - still experimental (early version)

• Load custom analyzers with --analyzer-path MODULE[:CLASS]; enumerate built-ins and discovered externals with --list-analyzers.
• Zero-config discovery (drop-in directory + entry points) now works across the Python API, CLI, and TUI.
• Docs: [Plugins & Custom Scripts](https://fkie-cad.github.io/friTap/development/plugins/).

• Offline Replay

• Offline decryptors are now resolved through a pluggable registry (tls, mtproto, telegram, …).
• Added --show-layers to print each decrypted flow's protocol layer stack.
• Added reusable, stateless HTTP/2 DATA-frame and RFC 6455 WebSocket de-framers (enabling -over-HTTP/2 recovery).
• Docs: [Offline Quick Start](https://fkie-cad.github.io/friTap/getting-started/offline-quickstart/), [Offline pcap to .tap](https://fkie-cad.github.io/friTap/advanced/offline-pcap-to-tap/).

• TUI & Packaging

• New a pcap→.tap conversion wizard and decrypt-confirm / open-pcap modals. This helps to analyze plaintext pcap directly with fritap.
• Added requirements-minimal.txt for a lean install, alongside a large expansion of unit and integration tests.
• Docs: [Interactive TUI](https://fkie-cad.github.io/friTap/getting-started/tui/).
